Apple can make calls like this based on how many people are still using the software and how severe the security issues are. You can do a good amount of disk cleanup on your own, and there are some excellent programs (both free and commercial) which can help you with those tasks. In November of 2020, Apple issued a security update for macOS High Sierra, even though it was three versions behind the latest release (Big Sur) at the time. Upgrading from an older version of macOS If you’re running High Sierra (10.13), Sierra (10.12), or El Capitan (10.11), upgrade to macOS Catalina from the App Store. Click Upgrade Now and follow the onscreen instructions to begin your upgrade. (You are making backups to an external device, right?)įinally, when you begin this process, you might want to do as much disk cleanup/maintenance as possible. Go to Software Update in System Preferences to find the macOS Catalina upgrade. In this case, you can go to the Mac App Store.
And the easiest way to do that is to use SuperDuper! or Carbon Copy Cloner to make a bootable backup. If your Mac runs macOS High Sierra 10.13 or earlier, theres no Software Update option in System Preferences. But upgrading might not be as "safe" or "OK" as doing a clean, fresh installation of the new OS, and then migrating/copying needed files, folders, settings etc. Download The macOS High Sierra 10.13.2 update improves the stability, compatibility and security of your Mac, and is recommended for all users. Maybe skip 2 of them and upgrade to Yosemite. I would advise not skipping "too many" of the various versions. Third, you need to be concerned about any third party software you are using, and most likely, will need either to upgrade some/most/all of them to be compatible with the OS you want to move to, or possibly some of them might not work at all.įourth, for High Sierra, Apple introduced the APFS file system, so that could be a challenge. Secondly, there are 6 more recent versions you could install: First off, you are running OS 10.7.5, which is Lion.
